UNITED STATES ULYSSES F. OLEMONS, OF MARSHALL, OKLAHOMA.

APPARATUS FOR REFINING HYDROCARBON OILS.

Application filed June 7, 1923. Serial No. 643,913.

To all whom it may concern:

Be it known that I, ULYSSES F. CLEMoNs, citizen of the United States, residing at Marshall, in the county of Logan and State 5 of Oklahoma, have invented certain new and useful Improvements in Apparatus for Itefining Hydrocarbon Oils, of which the following is a specification.

This invention relates to certain new and useful improvements in apparatus for refining hydrocarbon oils and more particularly is an improvement upon my Letters Patent No. 1449734 dated March 27, 1923.

In my prior'patent, the bed of fullers earth extends throughout the entire area of the tank with the result that the capacity of the still as reduced.

The present invention has for its primary object to provide a still of maximum capacity and accordingly proposes a still with an enlarged dome, both as to diameter and height, which is equipped with a floor supporting a bed of fullers earth.

A further object of the invention is to provide means for preventing the fullers earth from dropping down from the dome and into the body of oil contained in the tank.

In the drawings Figure 1, is a side elevation of the invention, parts being broken away and shown in section, and

Figure 2, is a section on line 22 of Figure 1.

In proceeding in accordance with the present invention a tank 1 is employed heated by oil burners 2 or other suitable means.

The tank is provided with a dome 3 of suitable diameter and height and which exceeds the usual diameter and height of domes of ordinary construction with which tanks of this type are generally or usually equipped.

A foraminous fioor 4 is provided for the dome and upon which is supported a bed of fullers earth 5. a

As illustrated more particularly in Figure 2 of the drawings, the sides 6 of the dome are parallel and extend considerably below the top 7 of the tank, so as to afiord a dome not only of increased height, but one possessed of a diameter nearly approximating the diameter of the tank. It will also be noted that the vapor space 8 below the floor 4 is of the same and full depth as-the vapor space existing between the top 7 of the tank and the level. of the crude petroleum or hydrocarbon oil 9 contained within the tank. In this manner the entire area of the floor 4, which latter is itself of relative considerable area, is completely exposed to the vapor.

For the purpose of preventing the fullers earth in the dome from dropping down mm the oil in the tank, a pan 13 is rovided which is suspended by hangers 14 rom the top of the tank so as to afford inlets 15 through which the vapor passes in entering the dome. The pan is of a size greater than the diameter of the dome so as to effectually catch any particles 01'' the fullers earth which may drop from the dome.

A condenser is connected by a pipe 11 to the top of the dome, the pipe having an automatic check valve therein which opens upon a predetermined ressure of vapor being reached in the tanli.

What is claimed is An apparatus for refining crude petroleum and hydrocarbon oils, including an oil tank, heating means for the tank, a dome for the tank of large diameter and height relative to the tank and having opposed sides which extend considerably below the top of the tank, a foraminous floor for the dome arranged so that the space between the floor and the surface of the oil in the tank is of the same depth as the space between the surface of the oil and the top of the tank, a bed of fullers earth on the floor, an outlet at the top of the dome, a pan in the dome in spaced relation to and beneath the floor so as to catch any particles of the earth droppin from the dome, and means to connect sai pan to the tank whereby to afford spaces between the margin of the pan and the top of the tank to permit the vapors to enter the dome.

In testimony whereof I aflix my signature.

ULYSSES F. CLEMONS.
